Meanwhile, the average selling price of a MacBook rose almost $100 to $1,419 on a sales drop of 6 percent.

Upshot: Both Windows lappies and MacBooks saw sales decrease, but Apple made a $100 average selling price gain versus a couple of bucks for Windows.

Maybe a bigger part of the Windows sales problem is that the mix of systems has changed compared with the glory days of Windows 7.

That is, Windows 7 was accompanied by a crush of ultracheap netbooks, according to an analysis at the Supersite for Windows -- which had some harsh words for netbooks.

"Many of those 20 million Windows 7 licenses each month -- too many, I think -- went to machines that are basically throwaway, plastic crap. Netbooks didn't just rejuvenate the market just as Windows 7 appeared, they also destroyed it from within," Paul Thurrott wrote.

"Now consumers expect to pay next to nothing for a Windows PC. Most of them simply refuse to pay for more expensive Windows PCs."

And, by the way, shipments of systems powered by Intel's power-efficient-yet-lower-performance Atom chip -- the same class of processors used in netbooks -- are barely a trickle at this point. And to make matters worse, some, like the $849 HP Envy x2, are priced way above the $399 netbooks of holiday seasons past.

There is a counterpoint to the NPD report, however. Analysts have told CNET that demand for touch-screen Windows 8 PCs in the U.S. is strong. Rhoda Alexander, an analyst at IHS iSuppli, told CNET last month that some vendors can't keep touch-screen PCs on the shelf.

So, if supply of touch-screen displays eases and system prices drop a bit, that could drive more sales. And prove to be an advantage over Apple, which doesn't have any touch-screen MacBooks.

At $749, Samsung's Intel Atom chip-based ATIV Smart PC is about $300 more than a Windows 7 Netbook.
